MACHINE FOR STAMPING WORKMENS INDIVIDUAL CARDS.

Application filed November 27, 1917.

To all whom it may concern:

Be it known that we, KARL AUGUST ALBERT LEHMANN, a citizen of the Republic of Switzerland, residing at Biel, Switzerland, and CONRAD SCHINDLER, a citizen of the Republic of Switzerland, residing at Pfafers, Switzerland, have invented certain new and useful Improvements in Machines for Stamping VVorkmens Individual Cards; and we do hereby declare the following to be a clear, full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in machines for stamping workmens individual cards.

The object of the invention is to provide a machine of the kind referred to, in which a type-mechanism, together with a mechanism adapted to impart a feed movement to the type wheels, is mounted on a shaft adapted to be rotated about its own axis, and in which a cutting mechanism determining the position of the records to be printed on the card is positively connected in such a manner to said shaft, that the type-mechanism and the cutting mechanism are simultaneously released on an insertion of the card to be stamped into the machine.

A further object of the present invention is to provide a stamping machine, in which the cards are guided in such a manner by a member cooperating with a cranked portion of the cards, that the releasing of the typewheel mechanism and the cutting mechanism is effected always at the right moment with regard to the position of the card to be stamped, this releasing being brought about quite independently of the length of the card-strip extending on one side of the cranked portion of the card to be stamped and of the width of the latter.

A still further object of the invention is to provide a stamping machine of the hereinbefore mentioned type, in which the feed mechanism for the type-wheels is constructed in such a manner, that the power required Specification of Letters Patent.

for imparting a feed movement to said wheels is not great enough to cause an inaccurate adjustment of the type-wheels, and in which the latter are securely fixed in the proper position as well in their position of rest as also in those cases, where two or more type-wheels have to be moved simultaneously relatively to each other.

This invention will now be more particularlydescribed with reference to the accompanying drawings, which illustrate a constructional example of the invention. The machine shown is constructed, for instance, for the insertion of one card onlv.

Figs. 13 and 14 show on an enlarged scale details of the feed mechanism for the typemechanism. Figs. 15, 16 and 17 illustrate a device for preventing a time-mechanism from impart which they take up previous to the actuation of the machine; Fig. 16 shows the parts in the stamping position and Fig. 17 in the position, which they assume, when the card has been stamped, but before the main shaft has been returned into its initial position by means of a hand lever.

Figs. 18, 19 and 20 illustrate modifications of details, and

ig. 21 shows an enlarged view of a detai The machine illustrated on the accompanying drawings is adapted to record on an individual card 1 (Fig. 7) a determinate point of time by means of the type-mechanism. The latter is acted upon by an electric clock not shown on the drawings. This clock is of well known construction and sends at determinate time intervals electric currents into a device electrically connected therewith. These currents impart in the manner hereinafter described a feed movement to the type-Wheels, so that the latter may record the hours, the quarters of an hour and theininutes on the individual card inserted into the machine. Such a time recording is required in all those cases, where the beginning and the end of the Working hours, or the beginning of a certain job, or the presence of the owner of the card has to be recorded automatically, 2'. e. in a manner excluding any mistake and so that the recorded time can not be wiped out. In order that one and the same card may be used several times, it is, however, essential, that the stamping of the card is efiected in such a manner, that a fixed distance between the printed lines is automatically secured. To this end, we have provided in our machine in connection with the type mechanism a cutting mechanism which on each actuation of the machine, 2'. e. each time that a line is printed fsevers aportion from the card, "the dimensions of this severed, portion corresponding to the distance betweentwo succeeding' 'stamped lines of the'card. Referring now to the drawings, 3 denotes a plate supported by four members 1 fixed to a base-plate 2. To the plate 3 are fixed two bearings 5 in which is rotatably,,,supported a main shaft 6.. To the latterisfixed a sleeve 7 provided with a hand lever 8. A spring 12 is connected at one end to a projection 9 of this lever 8 and at the other end in a 'suitable manner to the plate 3. The sleeve 7 has an extension 10 carryinga hardened catch 11 adapted to cooperate with a catch '13 (Figs. 2 and 3). Catch 13 is influenced by an electro-magnet 14 and it usually keeps the parts of the machine in the position which they take up previous to the. actuation of the machine.

On the main shaft 6 is pivotally mounted a printing or type-mechanism comprising a frame 15. In the end of this frame shown in the drawings on the left hand side is rotatably mounted a pin 16 (Figs. 1, 2, 12). On the latter are mounted for instance three type-Wheels 17, 18 and 19 (Fig. 2). Each of thesetype-wheels is rigidly connected to a toothed disk 20, 21 and 22 respectively. 17 18 and 19 are three feed-levers. Lever 17? cooperates with the feed-disk 20, 18 with the disk 21 and 19 with the disk 22.

To the type-wheel 17 is also rigidly connected. a disk 23.; (Fig. 2) and to the typewheel 18 a disk 24:. Each of these disks 23 and 24 has a notch. These notches are not shown'on the drawings; they are adapted to be engaged by the feedlevers 18 and 19 respectively, for the purpose of imparting to "the 'disks18 and 19 a feed movement corresponding to the distance between two 1et ters of the type-wheels, each time that the latter have completed one revolution. 7

, With each of the hereinbefore described feed-disks 20, 21 and 22, cooperates also a locking pawl 25 (Figs. 1, 12, 13 and let) and 26, 27 (Fig. 14) respectively. These pavvls 25, 26 and '27 are adapted to fix the type-wheels 17, 18 and 19 in their proper position and they are loose on a pin 28 mounted in the frame 15. 29 denotes a plate bearing on a pin 30 (Figs. 13, 1 1) which is also mountedin the frame 15. The arrangement is such, that the locking pawls 25, 26 and 27 are in contact with the plate 29 and effect an oscillation of the latter as soon as they re caused to exert a pressure onsaid plate 29. The locking p'awls 25, 26 and 27 project thro-ughslots 31 provided in the plate 29. 32 denotes tension springs. Each of. the latter is connected at one end to the plate 29 and at the other end with onef of the locking pawls 25 and 26, 27 respectively. The preliminary tension and the strength; these springs "32 are relatively small. J he springs, 32 :are adapted to set the locking pawls 25, 26 and 27 to operative position by pressing these pawls toward the feed-disks 20 .a'nd 21, :22 respectively.

Resilient tongues 33 (Fig. ,2) of a plate 34 cause-the feed-levers 17 18 ,19 to engage thefeed-disks 20, and 21, 22 respectively. Said tongues 33 are connected to a magnet core v35 actedziupon by a spring '36. The magnetcore 35 is influenced'in its turn by an electromagnet. 37 which is electrically connected to'the clock hereinbefore referred to and not shown on thedrawings. A stirrup -like, resilient member 38 passing through the main shaft 6 (Figs. 1 and 12) is adapted to act upon the frame 15 carrying the type mechanism on a rotation of the shaft..6 for the purpose of tilting this frame 15. 39 denotes the ink-pad. The typewheels '17, 18 and 19 are caused to touch this pad39 when they are oscillated about the shaft 6 before they are pressed against the card 1 to be stamped.

The operation of the hereinbefore described feed mechanism is as follows: I

Each time that the electromagnet 37 is energized, the magnet core 35 is attracted by it. The free ends of the feed levers 17 18 ,19 then slide over the teeth of the disks 20, 21 and 22 respectively, with which they are just in engagement, disengaging thereby said teeth and dropping upon the immediately succeeding tooth of these disks. The type-wheels 17,- 18 and 19 are fixed during said movement of the feed-levers in their proper position by the locking pawls 25,

26 and 27. As soon as the current flowing through the electromagnet 37 is interrupted, the spring 36 has the tendency to move the core with regard to the gures toward the left and the feed-lever 17 .and correspondingly also the feed-levers 18 19 in the case, that a feed movement of the typcwheels 18 and 19 has just to be effected-is forced into the gap lying between the tooth over which the lever has just been moved and the tooth which is now engaged by this lever. On a further movement of the core 35 toward the left, the disk '17, together with the feed-disk 20 is then moved in the direction of the arrow A (Fig. 13). This rotation causes the locking pawl 25 to oscillate in the direction of the arrow B about the pin 28, so that the plate 29 rotates in the direction of the arrow C (Fig. 13) about the pin 30 acting as a pivot for said plate 29. Thereby the spring 32 connected to the locking pawl 25 is wholly tensioned, while the remaining two springs 32 are only partially tensioned.

It will be seen, that in this arrangement it is necessary to overcome, besides the friction produced in the bearings for the type wheels during each feed movement imparted to them, no matter if one, two or three typewheels have to be moved simultaneously through a certain angle, onlythe resistance, which the plate 29 influenced by the springs 32 opposes to a rotation about its pivot 30 when it is acted upon by the locking pawls 25, 26, 27.

As, however, the preliminary tension and the strength of the springs 32 are relatively small, the power required for imparting a simultaneous feed movement to two or three type-wheels is not Very much greater than that required for imparting feed movement to only one of these wheels. As soon as the feed-levers 17 18 19 have brought about the required rotation of the type-wheel or the typewheels, the locking pawls of the type-wheels which have been rotated, engage'the next tooth space of the feed -disks 20, and '21, 22 respectively, rigidly connected to the type-wheels, in

order to fix these disks 20, 21, 22 in their proper position. The power with which the locking pawls 25, 26, 27 are caused to engage the feed-disks and the fixing power, 2'. e. the power with which the locking pawls are kept in engagement, remains substantially also always the same, no matter if one, two or three type-wheels have to be rotated simultaneously. Thus, the power with which the locking pawls tend to engage the feed disks depends only on the power with which the plate 29 tends to move back into its initial position under the influence of the springs 32, and this power remains substantially the same when one, two or three typewheels have to be moved.

The hereinbefore described manner of operation of the feed mechanism is wholly independent of the number of the typewheels, 6. e. of the wheels provided with numbers, letters or marks, which may be arranged in the type mechanism.

The cutting mechanism comprises a rail 40 '(Figs. 1, 2, 4, 5, 6, 11) provided with two slots 41 and 42 (Figs. 5, 4, 1'1) and cooperating with a member 43. A bolt 44 mounted in a plate 45 (Figs. 4, 5) fixed to the plate projects into the slot 41. The slot 42 arranged concentrically to the mainshaft 6 cooperates with a bolt 46 rigidly connected to a crank arm 47 fixed to the main shaft 6. The front end of the rail 40 has a part 48 (Fig. 11) arranged substantially at right anglesto the main body of this rail 40. 5O denotes a knife pivotally mounted on a bolt 49 fixed to the rail 40. The part 48 acts as a counter-piece or matrix for the knife 50. The rear end of the latter has a slot 51 (Figs. 11, 4, 5) through which passes the bolt 46' and which is so shaped, that.

upon rotation of the shaft 6 the bolt 46 causes the knife 50 to pivot about bolt 49 in order to sever a cutting from the card 1. The arrangement and the shape of the slots 41, 42 and 51 are such, that they admit in their foremost position a short displacement of the rail 40 and knife 50 in the di rection of insertion of the card 1 without causing a tilting or a rotation of the knife 50, a movement which would then prevent any further insertion of the card 1.

The rear end of the rail 40 is adapted to act upon a contact spring 52 (Fig. 2) by means of the member 43. On a rearward displacement of the rail 40, .the contact spring 52 is pressed toward a contact 53. As a result of this, the current energizing the electromagnet 14 is closed. The contact spring 52 acts indirectly also as a spring upon the knife, so that a proper breaking of the contact and a certain resistance against a too easy contact-making is obtained. The parts 40, 50 are moved in their longitudinal direction on an insertion of the card to be stamped into the machine, the card efiecting thereby also the actuation of the electromagnet 14.

In order to obtain a correct stamping of the card, it is essential, that the releasing of the type-mechanism and the cutting mechanism is effected each time in the proper position of the card to be stamped. This position depends, however, largely on the guide member of the card, so that this guide member is of very great importance.

Forthe purpose of guiding the card to be stamped in an accurate manner, the machine illustrated on the drawings comprises a plate 54; (Fig. '10-) fixed to the plate 3.

- This plate 54: has a recess extending over its whole length. To the bottom side of the plate 5 1 is secured a further plate 55, a part of which is bent substantially at right anglesu 'iivard. The plates 5 1, form between them a slot 56 (Fig. '10) adapted to receive the cranked portion of the card 1. The latter may be cranked in the manner shown by folding it in a suitable manner. The surfaces of the plate 55 coming in contact with the card 1 effect an accurate guiding of the card 1. The accuracy with which the card 1 is guided by the plate 55 isthereby wholly independent ofthe contraction of the card taking place in consequence of the severing of the cuttings along one of the edges of the card or of the Width of the latter. The plate acts simultaneously as afront stop for the rail 40 when the latter is moved in its longitudinal direction.

57 denotes pins adapted to act as guides for the card 1 in all those cases where its width exceeds a certain measure. The pins 57 areprovided on a plate'58 (Fig. 9) which is fixed to the inside of a removable cover 59. The latter is for inclosing the difi'erent mechanisms of the machine. The plate 58 has 'a'slot for inserting the card 1. The plate-3 is provided with the recesses and openings required for the proper movements of the different parts of the mechanisms.

7 shows the cranked end of the card 1. The recess '61 of this card is for preventing a printing ofthe right end of the card, asthis end is reserved for the printing of notices relating to the name of the firm, the section of the works, the name and numher or the workman, or the like. The dotted lines in Fig. 7 show the cuttings gradually severediirom the card in the course of v the stamping of the latter, in order that the required distance between the different stamped lines may be'obtained.

The working of the machine is as follows: When the hand lever 8 has been'turned from the right to the left into the position shown in Figs. 2, 3 and 4c, the catch 11 is caused to engage the catch 13. Thelatter then locks the catch 11. The spring 12 has been tensioned in consequence ofsaid movement imparted to lever 8, and the different parts are now in the position which they assume previous tothe actuation of the ma chine, this being the normal'position of rest.

lVhen it is desired to effect a time record, the card 1 to be stamped is inserted-into the guide-slot 56. As soon as this card is pushed against the knife 50, it moves the latter togetl'ie'r with the rail 10 rearward until the spring'52 is caused to touch the contact'53, inwhioh case the circuit for the current energizing the electromagnet 14 is closed. (living to this, "the "catch 13 is then released and the tension s ring 12 causes thesl'eeve 7, provided with themtch ll-and fixed to the slant 6, "to tu'in quickly about its own axis. This rotation of the "shaft 6 causes an oscillation: of the crank 47 er the cutting mechanism, the bolt 46 rigidly connected to the crank 47 effecting thereby a retation of the lmife'50'aboiit bolt 49. As a result ofthis, the knife 50 is moved from the position shown in Fig. into that shown in Fig. '5, whereby a cutting is-severed from that portion of the card 1 which rests on the counter-piece or matrix K18, the cutting severed 011' "corresponding tojthe' distance between the lines of the records to be printed. The type-mechanism loose on the shaft 6 remains, owing to the great load of the mag net 37 arrangedo'n one si'de of the'fra 'ne' 15, in its position of rest untilthestirrup 38 rigidly connected to the shaft 6 strikes against the frame 15, when this resilient stirrup 38 then causes the type-mechanism to tilt about the shaft 6 and stamp the required record on the card 1 'res'tin'gonthe support 62 (Figs. 12, 1) The resilient stirrup 38 pressing the card 1 against the support 62 prevents, during theeta mping, any shifting ofthe card 1 in' its direction of insertion. Fig. 12 illustrates the parts "in'the-stamping or printing position. Immediately after the striking of the type-mechanism againstthe stamping card, the frame 15 carries out a small backwardpscillation relatively to the stirrup 38 until it comes to rest on the rear end ofthe'stirru ss. Any -accidental too early pulling out of the card does not interffere with "the propenworking "of the inachine. I

The parts of th'e 'niachinethen remain in the position justuescribed, until the main shafts is returned "into itsinitial position by means ofthe lever'S. 'When this 'is'done, the fcar'd can be pulled out, the different mechanisms 'ofth'e machine being again in the position which they assume previous to their actuation.

Figs. 15, 16 and '17 illustrate a device for preventing t-heclock hereinbefore referred to from imparting a feed movement to the type-mechanism while the latter stamps the card. but without causing the loss of the temporary prevented feed movement. Y

Referring to these Figs. 15, 16 and 17, denotes a pawl pivotally mounted on a pin 71 carried by the frame 15. The pawl 70 has a recess 72. The right hand end of this pawl. 70 has the tendency to move downward under the action of gravity. 73 is a resilient stop fixed to the plate 3. The pawl 70 provided on one of its ends with a pin 7%, assumes previous to the operation of the machine the position shown in Fig. 15. The frame 15 has a pin 75.

When the stamping is taking place, the frame 15 is in the position shown in Fig. 16, it being then for a short moment, owing to the tilting force imparted to it, at a certain distance from the rear end of the stirrup 38. As soon as the frame 15 is moved from the position shown in Fig. 15 into that shown in Fig. 16, the pawl 70 changes its position as well relatively to the stop 73 as to the frame 15. The pin 76 mounted in the core 35 (Fig. 2) of the electromagnet 37 strikes, on the tilting of the frame, against the left hand end of the pawl 7 0 (Fig. 21) and presses this end into the position shown in Fig. 16, the stop 73 being bent toward the left by the pin 74. Should it now occur, that a current impulse passes through the electroma-gnet 37, the pin 76 drops into the recess 72 as soon as the core 35 is pulled inward. Thereby, an outward movement of the core 35, and therefore a feed of the typewheels is prevented as long as the parts assume the position shown in Fig. 16. However, this is only the case for a short moment, as immediately after the striking of the type-mechanism against the card, the frame 15 effects a small relative movement with regard to the stirrup 38 until it comes to rest on the rear end of this stirrup 38 (Fig. 17). In consequence of the resistance produced between the stop 73 and the pin 74, the pawl 70 is substantially prevented from carrying out any movement. The result of this is, that the pin 76 is in the position of the frame 15 shown in Fig. 17 wholly out of reach of the pawl 70, so that the core 35 can now complete its interrupted to and fro movement. The core 35 is also adapted to carry out later on in this position of the type-mechanism such a to and fro movement, should the mechanism have been left through inadvertence in the position shown in Fig. 17.

When the main shaft 6 ismoved back into the position shown in Fig. 15 by means of hand lever 8 (Figs. 2, 3), the pin of the frame 15 strikes against the pawl-7O and causes thereby a rotation of the latter about the pin 71 in a clockwised irection, the last part of thismovem'ent being only brought about by the gravity acting on pawl 7 0, s0

that pin 75 disengages again the pawl 70. As soon as the pin 74 strikes against the stop 73, the pawl 7 O is prevented from further rotating in the direction referred to.

When the cards to be used have not a cranked portion, but are provided, for instance, with a Q or A shaped recess, the shape shown in Figs. 18 and 19 respectively, is given to the part 55 acting as a guide.

When desired, the cranked card may also be replaced by a card-holder 65 (Fig. 20). On one side of such a holder is then fixed a thin sheet of paper 66 on which the records may be stamped, while on the other end is fixed a narrow, stifi' strip 67 from which the cuttings may be severed. The holder 65 comprises also a part acting as a guide for it and which has, for instance, the shape of an arm 68 cooperating with a correspondingly shaped part of the plate 55.
